如何在休眠映射文件中定义存储过程的调用，然后从Java（MSSQL服务器）调用它

Question

I need to call stored procedure in java code ( entityManager is available only). This stored procedure should be defined in some hbm.xml file.

I didn't find any solution how to do it.

In hibernate documentation I found that it should be declared in this way.

<sql-query name="InsertTestCaseData" callable="true">
    { ? = call dbo.InsertTestCaseData(:ID) }
</sql-query>

This procedure returns only result code ( mssql server ). how should I describe it in mapping file? And how to handle if this procedure returns some value of some column, should I define <return-property> in hbm file?

I have only entityManager object. there is no method like getNamedQuery() .

What method could be used instead?

And where mapping file should be located? Could it be separate file with queries only?

There are few examples for you here but here is how you would call a stored procedure using entity

// This stored procedure returns a result set and has one input parameter.
@NamedStoredProcedureQuery(
    name = "ReadAddressById",
    resultClasses = Address.class,
    procedureName = "READ_ADDRESS",
    parameters = {
        @StoredProcedureParameter(mode=IN, name="P_ADDRESS_ID", type=Long.class)
    }
)
@Entity
public class Address {
  ...
}
